I’m not a competitive runner, but I’ve always run. I run mostly to be fit for my climbing and to keep my weight down. Over the last few years, however, I’ve been running for the sheer love of it, the movement and the health benefits. I even enjoy road running! It has to be pretty wet though (or a recovery run) for me not to choose to run on trails or through the mountains. I’m not some super athlete, I’m a 55 year old dad who was once quite good at rock climbing but whose focus has changed – it’s now about longevity and being fit and healthy enough to continue climbing and running into my 60’s, 70’s and beyond. Running through the mountains is a big part of that and running in winter an even bigger part.

Why would you want to run in such a hostile environment?

Winter in the UK uplands is very harsh, even if it isn’t snowing the temperatures can be below freezing; the wind seems to cut through every layer you have on, your hands feel like blocks of wood and every rock you land your feet on seems to be covered in slime. But on that special day, when the wind is at your back, you’re running along a plateau, the clouds roll back and the sun shines on that white neve (snow that has thawed and refrozen), which gives awesome friction and you just seem to glide over it; those are the special days and worth every bucket of sweat to achieve. Mostly though, winter running in the mountains involves a lot of sweat, gnarl, pain and suffering – oh and getting wet!

Perfect winter conditions – be warned though it can change in an instant.

So now I’ve persuaded you of the joys of running through the mountains in winter (haven’t I?) what do you need to know to get yourself into it? Well, it is very different to summer as you can imagine, with the weather being your main opponent. It can change in an instant with very little warning and no amount of weather forecasts can guarantee you the weather you’ve seen on your laptop or phone screen.

I have found that the MWIS (Mountain Weather Information Service offers the best forecast for UK mountain conditions. They’ve been doing it for many years and have a great team of forecasters who work closely with the Met Office. So for planning I use MWIS and then I use the Met Office app for more up to date information on the day and by the hour if needed. Still, I have lost count of the times I’ve cursed the Met Office when I’m looking at the sun/ cloud icon on my phone in the rain! So that brings me onto what you should be aware of if you are thinking of venturing out into the mountains this winter.


You should never go out into the mountains (in summer or winter) without the ability to navigate competently using a map and compass. A quick look at the Mountain Rescue stats will highlight what happens those who do venture out without that ability.

The fact that we are out running, moving light and carrying minimal kit means that we need our day to go smoothly and knowing where we are and where we are going is the difference between an enjoyable and challenging experience, as opposed to having an epic. Don’t get me wrong, I use my phone for location all the time and I also use it to help me know that I’m going in the right direction but I don’t rely on it. I know, from bitter experience, that that leads to it dying when I most need it so it usually stays on airplane mode and I only get it out when I need it. That means most of the time I’ve got just my map and compass out, which I’ve printed off from my OS Maps subscription onto waterproof map paper.

I’ve also found the BMC Mountain maps very good (but I like to have 1:25000 as it ties in with the maps on my phone). For a compass I use the Suunto Arrow 30, it’s a good compass which works brilliantly (I have three top of the range Suunto compasses but this is my compass of choice for personal use).

Suunto Clipper Compass

I also have a Suunto Clipper Compass permanently on the sternum strap of my pack as I often don’t need the full compass and just want a quick north bearing so I can orientate my map and choose which path I need to take. It’s also a good idea to have all your critical directional bearings drawn on your map with permanent marker so you can just set the compass and go.

Clothing & Packs

Winter running poses more demands on our clothing systems than in summer. That said we are running so we don’t need to take all those extra layers we might take on a hike. Versatility is key and layers which we don’t need to be taking on and off all the time work best.

Top & Bottom

My preference is for a good pair of winter running leggings (the Montane Cordillera Thermal Trail Tights are good). I’ll then have a good quality pair of boxers under them (the Rab Merino Merino Plus 120 are great as they are a little warmer) and a pair of shorts over the top of the tights (the Arc’teryx Adan Shorts work well). That won’t keep the wind out though, if you want to be more windproof I would suggest a pair of Gore Windstopper tights (I use Arc’teryx Trino tights).

Arcteryx Squmish Hoody

On my torso I have a winter weight thermal (the Patagonia Capilene Thermal Weight Zip Neck). I’ll start the run with that on and probably get quite hot when I start going up, as the wind gets up (which it often does) I’ll then pop on a windproof jacket, I love my Arc’teryx Squamish and prefer it to the Incendo Hoody as it’s more of a mountaineers windproof and a little thicker. I always make sure to preset the hood at home so that I’m not having to faff around when that wind blowing me around on the summit.

I will also have a superlight hardshell in my pack for extra protection against hail, rain and horizontal snow (the Rab Kinetic Plus is ideal). This will be in my pack most of the time though, if I’ve planned my day right of course! I’m not one for carrying waterproof pants, although I do use the Montane Minimus Pants if it’s forecast to snow hard.

One item of clothing I never skimp on for winter is a decent insulating jacket. For UK weather, I always opt for synthetic fill as our weather is too damp for down. I’m not saying a full on Scottish winter climbing belay jacket is needed, but it does need to be good enough to keep you warm when the proverbial hits the fan. Also, it’s nice to have a warm layer when you stop to take in the awesome view for a few minutes. I know that some might feel that it takes a lot of room up in the pack but I prefer to have that safety margin. Hobbling down with a twisted ankle takes a lot of time – you might as well be warm!


Hestra Ergo Grip Active

Other clothing essentials to consider are gloves (I like 3 pairs in winter); 2 pairs of Rab Silkwarm and a pair of Hestra Ergo Grip Active are my gloves of choice. This works out as a pair to warm up in, the Hestra for the summit run and a dry pair for spare or to use on the way down. I also like a nice lightweight hat or even a headband. Merino may be a little warmer but will not dry as quickly as PowerStretch. For socks I like to wear compression long socks if the weather forecast is dry and ground conditions are likely to be good but for snow or wet ground I’ll wear waterproof socks as well as Gore-Tex shoes.


Arcteryx Norvan VT GTX

Talking of shoes, ideally they need to be a little stiffer that a normal running shoe so look for a more specialist shoe. Arc’teryx have been making great inroads into the trail running shoe market and the new Norvan VT GTX look brilliant with their climbing and scrambling ability. Why stiffer? Well for some of the day you may need to be wearing spikes or even lightweight crampons (if you are planning to get into some steeper ascents/descents).

Also remember that snow will get into shoes easily so you’ll need a set of gaiters to keep your feet drier and warmer (they will never be completely dry). For winter I’m not a fan of the sock type gaiter as I’ve trashed them after only one run so something a little burlier like the Rab Scree Gaiter is better. You only want a short gaiter as it’s more breathable and I find a full gaiter is too hot and cumbersome.

Softer ground will need a good supportive shoe. An integrated gaiter works really well.


I use a 15L pack if I need more I’ll add a belt. I’ve been using an Ultimate Direction Fast Pack 15 with a Salomon Advanced Skin 6. There’s also the excellent Inov8 All Terrain Pro Vest, this has the advantage of the main pack being removable so you can use it as a normal race vest for lower level trail running.

Inov8 All Terrain Pro Vest

The most important thing is that the pack doesn’t sway around or move on your back. This may be a bigger and heavier pack that you are used to carrying so make sure it has plenty of shock cord and compression straps to keep everything tight in the pack. The Inov8 All Terrain 3 looks a nice waist pack and it can be worn either at the front or the back. I like to keep some liquid, a few bars and my wind proof in my waist pack if I’m using one and I’ll take it if the weather looks iffy and I need to pack more.

That covers the clothing essentials as well as a pack – all super light and compressible. I’ll also spend many evenings looking at how it all packs together and how I can access it when needed. The secret to clothing is anticipation, it’s no use trying to put that extra hardshell on when a gale is blowing on the summit; stop for a few minutes just below where it’s calmer and put it on then.
